Abstract
A microwave oven defrosts a food item by subjecting the food item to a first defrosting stage during which a flow of air is forced through the oven cavity by a fan, and microwave power is simultaneously delivered to the cavity, ceasing the first stage when the temperature of the air flow reaches a threshold value and subjecting the food item to a second defrosting stage during which the air flow is maintained continuously and the microwave power is pulsed in accordance with a pre-set program.
